ISIS claimed responsibility via its news agency Amaq for a series of terrorist attacks, which hit Indonesia on May 13.
At least 13 people were killed and 40 others were injured after suicide bombers attacked the Santa Maria Catholic Church, the Indonesian Christian Church and the Pentecost Central Church in the port city of Surabaya, on Java Island’s east coast, according to police.
The attacks were conducted by a family of six.
Police also revealed that an unexploded device at an undisclosed location had also been “secured.”
Authorities blaimed blamed the suicide attacks on the ISIS-inspired group Jemaah Ansharut Daulah (JAD), which had allegedly drawn hundreds of ISIS supporters in the country.
The May 13 attacks came just a few days after militant prisoners killed five members of an elite counter-terrorism force during a 36-hour standoff at a high security jail on the outskirts of the country’s capital of Jakarta.
